Zoology - Breathing and Exchange of Gases Question with Solution | TestHub

Respiratory capacities are the volume of air present at each stage of the gas exchange process found in the human body. Total lung capacity is the amount of air one can accommodate$~5000\mathrm{ }\mathrm{m}\mathrm{L}$, vital capacity is the volume of air that can forced out$~4500\mathrm{ }\mathrm{m}\mathrm{L}$. The amount of air that will remain after normal exhalation is functional residual capacity$~2300\mathrm{ }\mathrm{m}\mathrm{L}$, and inspiratory capacity is the extra volume of air that can be inspired forcibly after after a normal inspiration is$~3000\mathrm{ }\mathrm{m}\mathrm{L}$.
